Background
With the development of communication technology, a traditional cloud computing power network is changing, and fig. 1 is an architecture topological diagram of the power network provided by the application, as shown in fig. 1, the power network includes a core cloud, an edge cloud, and a terminal, wherein the core cloud interacts with the edge cloud through the internet, and a terminal base station can interact with the edge cloud.
The core cloud is a traditional cloud computing power providing network, the distance from the core cloud to a computing power demand side is longer than the distance from an edge cloud to the computing power demand side, and the core cloud is usually used for executing non-high-frequency interactive computing requirements because the distance from the core cloud to the computing power demand side is longer. In addition, the core cloud is also used for storing data persistently and shunting and executing part of computing tasks of the edge cloud when the computing amount of the edge cloud is large. Fig. 2 is a schematic diagram illustrating a core cloud according to the present application, where as shown in fig. 2, the core cloud includes a plurality of working nodes and a plurality of gateways, and the gateways in the core cloud may communicate with the outside, for example, with an edge cloud.
The edge cloud is a computing power providing network formed by network nodes approaching a computing power demand side, the distance from the edge cloud to the computing power demand side is shorter than the distance from the core cloud to the computing power demand side, and the edge cloud is closer to the computing power demand side, so that the edge cloud is generally used for executing high-frequency interactive computing requirements, such as executing computing requirements of disaster early warning, telemedicine, video call or artificial intelligence processing. In addition, the core cloud is also used for temporarily storing data. Similar to the core cloud, the edge cloud also includes a plurality of worker nodes and a plurality of gateways, and the gateways in the edge cloud can communicate with the outside world, such as the core cloud.
The terminal is a calculation force demand party, such as a mobile phone, a camera, an automobile or an unmanned aerial vehicle, and the terminal can send calculation demands to the edge cloud or the core cloud through the base station so that the edge cloud or the core cloud can calculate.
When the edge cloud and the core cloud interact with each other, usually, the gateway in the edge cloud and the gateway in the core cloud interact with each other through the internet, and the gateway in the edge cloud or the gateway in the core cloud is easily tampered due to the openness of the internet, and after the gateway is tampered, wrong data can be sent when the edge cloud or the core cloud interacts with each other, or data can be sent to wrong objects, so that the safety of the edge cloud or the core cloud during interaction is seriously damaged.

In practical applications, the data transmission method provided in the embodiment of the present application may be applied to the first node 31, and may also be applied to a device included in the first node 31.
The following describes a data transmission method provided in an embodiment of the present application, taking an example in which the data transmission method is applied to the first node 31, with reference to the accompanying drawings.
